</p><p>Musicians play some string instruments, like <a href="Guitar" title="Guitar">guitars</a>, by plucking the <a href="String_(music)" title="String (music)">strings</a> with their fingers or a <a href="Plectrum" title="Plectrum">plectrum (pick)</a>, and others by hitting the strings with a light wooden hammer or by rubbing the strings with a <a href="Bow_(music)" title="Bow (music)">bow</a>, like <a href="Violin" title="Violin">violins</a>. In some <a href="Keyboard_(music)" class="mw-redirect" title="Keyboard (music)">keyboard</a> instruments, such as the <a href="Harpsichord" title="Harpsichord">harpsichord</a>, the musician presses a key that plucks the string.

</style><blockquote class="templatequote"><p>Chordophones are instruments with strings. The strings may be struck with sticks, plucked with the bare fingers or a plectrum, bowed or (in the Aeolian harp, for instance) sounded by wind. The confusing plenitude of stringed instruments can be reduced to four fundamental type: zithers, lutes, lyres, and harps.</p></blockquote>
<p>In most string instruments, the vibrations are transmitted to the body of the instrument, which often incorporates some sort of hollow or enclosed area. The body of the instrument also vibrates, along with the air inside it. The vibration of the body of the instrument and the enclosed hollow or chamber make the vibration of the string more audible to the performer and audience. The body of most string instruments is hollow, in order to have better sound projection. Some, however—such as <a href="Electric_guitar" title="Electric guitar">electric guitar</a> and other instruments that rely on electronic amplification—may have a solid wood body.

Most western instruments fall into the second group, but the <a href="Piano" title="Piano">piano</a> and <a href="Harpsichord" title="Harpsichord">harpsichord</a> fall into the first. Hornbostel and Sachs's criterion for determining which sub-group an instrument falls into is that if the resonator can be removed without destroying the instrument, then it is classified as 31. The idea that the piano's casing, which acts as a resonator, could be removed without destroying the instrument, may seem odd, but if the action and strings of the piano were taken out of its box, it could still be played. This is not true of the <a href="Violin" title="Violin">violin</a>, because the string passes over a bridge located on the resonator box, so removing the resonator would mean the strings had no tension.

<div class="mw-heading mw-heading2"><h2 id="Renaissance_to_modern">Renaissance to modern</h2></div>

<p>String instrument design was refined during the <a href="Renaissance" title="Renaissance">Renaissance</a> and into the <a href="Baroque_period" class="mw-redirect" title="Baroque period">Baroque period</a> (1600–1750) of musical history. <a href="Violins" class="mw-redirect" title="Violins">Violins</a> and <a href="Guitars" class="mw-redirect" title="Guitars">guitars</a> became more consistent in design and were roughly similar to <a href="Acoustic_guitar" title="Acoustic guitar">acoustic guitars</a> of the 2000s. The violins of the <a href="Renaissance" title="Renaissance">Renaissance</a> featured intricate <a href="Woodwork" class="mw-redirect" title="Woodwork">woodwork</a> and stringing, while more elaborate bass instruments such as the <a href="Bandora_(instrument)" title="Bandora (instrument)">bandora</a> were produced alongside quill-plucked <a href="Cittern" title="Cittern">citterns</a>, and Spanish body guitars.
</p><p>In the 19th century, string instruments were made more widely available through mass production, with wood string instruments a key part of orchestras – <a href="Cello" title="Cello">cellos</a>, <a href="Viola" title="Viola">violas</a>, and <a href="Double_bass" title="Double bass">upright basses</a>, for example, were now standard instruments for <a href="Chamber_music" title="Chamber music">chamber ensembles</a> and smaller orchestras. At the same time, the 19th-century guitar became more typically associated with six-string models, rather than traditional five-string versions.
</p><p>Major changes to string instruments in the 20th century primarily involved innovations in electronic <a href="Instrument_amplification" class="mw-redirect" title="Instrument amplification">instrument amplification</a> and electronic music – <a href="Electric_violin" title="Electric violin">electric violins</a> were available by the 1920s and were an important part of emerging <a href="Jazz" title="Jazz">jazz music</a> trends in the United States. The <a href="Acoustic_guitar" title="Acoustic guitar">acoustic guitar</a> was widely used in <a href="Blues" title="Blues">blues</a> and <a href="Jazz" title="Jazz">jazz</a>, but as an acoustic instrument, it was not loud enough to be a solo instrument, so these genres mostly used it as an <a href="Accompaniment" title="Accompaniment">accompaniment</a> <a href="Rhythm_section" title="Rhythm section">rhythm section</a> instrument.

Electric guitars have <a href="Magnetic_pickup" class="mw-redirect" title="Magnetic pickup">magnetic pickups</a>, <a href="Potentiometer" title="Potentiometer">volume control knobs</a> and an output jack.

Breakthroughs in <a href="Electric_guitar" title="Electric guitar">electric guitar</a> and bass technologies and playing styles enabled major breakthroughs in pop and rock music in the 1960s and 1970s.

<p><a href="Bowing_(music)" class="mw-redirect" title="Bowing (music)">Bowing</a> (Italian: <i>arco</i>) is a method used in some string instruments, including the <a href="Violin" title="Violin">violin</a>, <a href="Viola" title="Viola">viola</a>, <a href="Cello" title="Cello">cello</a>, and the <a href="Double_bass" title="Double bass">double bass</a> (of the <a href="Violin_family" title="Violin family">violin family</a>), and the old <a href="Viol" title="Viol">viol</a> family. The <a href="Bow_(music)" title="Bow (music)">bow</a> consists of a stick with a "ribbon" of parallel horse tail hairs stretched between its ends. The hair is coated with <a href="Rosin" title="Rosin">rosin</a> so it can grip the string; moving the hair across a string causes a <a href="Stick-slip_phenomenon" class="mw-redirect" title="Stick-slip phenomenon">stick-slip phenomenon</a>, making the string <a href="Vibration" title="Vibration">vibrate</a>, and prompting the instrument to emit sound. Darker grades of rosin grip well in cool, dry climates, but may be too sticky in warmer, more humid weather. Violin and viola players generally use harder, lighter-colored rosin than players of lower-pitched instruments, who tend to favor darker, softer rosin.<sup id="cite_ref-20" class="reference"><a href="#cite_note-20"><span class="cite-bracket">[</span>20<span class="cite-bracket">]</span></a></sup>
</p><p>The <a href="Ravanahatha" title="Ravanahatha">ravanahatha</a> is one of the oldest string instruments. Ancestors of the modern bowed string instruments are the <a href="Rebab" title="Rebab">rebab</a> of the Islamic Empires, the Persian <a href="Kamanche" class="mw-redirect" title="Kamanche">kamanche</a> and the <a href="Byzantine_lira" class="mw-redirect" title="Byzantine lira">Byzantine lira</a>.

<div class="mw-heading mw-heading4"><h4 id="Striking">Striking</h4></div>
<p>The third common method of sound production in stringed instruments is to strike the string. The piano and <a href="Hammered_dulcimer" title="Hammered dulcimer">hammered dulcimer</a> use this method of sound production. Even though the piano strikes the strings, the use of felt hammers means that the sound that is produced can nevertheless be mellow and rounded, in contrast to the sharp attack produced when a very hard hammer strikes the strings.
</p><p>Violin family string instrument players are occasionally instructed to strike the string with the stick of the bow, a technique called <i><a href="Col_legno" title="Col legno">col legno</a></i>. This yields a percussive sound along with the pitch of the note. A well-known use of <i>col legno</i> for orchestral strings is <a href="Gustav_Holst" title="Gustav Holst">Gustav Holst</a>'s "Mars" movement from <i><a href="The_Planets" title="The Planets">The Planets</a></i> suite.
</p>
<div class="mw-heading mw-heading4"><h4 id="Other_methods">Other methods</h4></div>
<p>The <a href="Aeolian_harp" title="Aeolian harp">aeolian harp</a> employs a very unusual method of sound production: the strings are excited by the movement of the air.
</p><p>Some instruments that have strings have an attached <a href="Musical_keyboard" title="Musical keyboard">keyboard</a> that the player presses keys on to trigger a mechanism that sounds the strings, instead of directly manipulating the strings. These include the <a href="Piano" title="Piano">piano</a>, the <a href="Clavichord" title="Clavichord">clavichord</a>, and the harpsichord. With these <a href="Keyboard_instrument" title="Keyboard instrument">keyboard instruments</a>, strings are occasionally plucked or bowed by hand. Modern <a href="Composer" title="Composer">composers</a> such as <a href="Henry_Cowell" title="Henry Cowell">Henry Cowell</a> wrote music that requires that the player reach inside the piano and pluck the strings directly, "bow" them with bow hair wrapped around the strings, or play them by rolling the bell of a <a href="Brass_instrument" title="Brass instrument">brass instrument</a> such as a <a href="Trombone" title="Trombone">trombone</a> on the array of strings. However, these are relatively rarely used special techniques.
</p><p>Other keyed string instruments, small enough for a strolling musician to play, include the plucked <a href="Autoharp" title="Autoharp">autoharp</a>, the bowed <a href="Nyckelharpa" title="Nyckelharpa">nyckelharpa</a>, and the hurdy-gurdy, which is played by cranking a rosined wheel.
</p><p>Steel-stringed instruments (such as the guitar, bass, violin, etc.) can be played using a <a href="Magnetic_field" title="Magnetic field">magnetic field</a>. An <a href="E-Bow" class="mw-redirect" title="E-Bow">E-Bow</a> is a small hand-held <a href="Electric_battery" title="Electric battery">battery-powered</a> device that magnetically excites the strings of an electric string instrument to provide a sustained, singing <a href="Tone_(musical_instrument)" title="Tone (musical instrument)">tone</a> reminiscent of a held bowed violin note.
</p><p><a href="3rd_bridge" title="3rd bridge">Third bridge</a> is a plucking method where the player <i>frets</i> a string and strikes the side opposite the bridge. The technique is mainly used on electric instruments because these have a pickup that amplifies only the local string vibration. It is possible on acoustic instruments as well, but less effective. For instance, a player might press on the seventh <a href="Fret" title="Fret">fret</a> on a guitar and pluck it at the head side to make a tone resonate at the opposing side. On electric instruments, this technique generates multitone sounds reminiscent of a clock or bell.
</p><p>Electric string instruments, such as the <a href="Electric_guitar" title="Electric guitar">electric guitar</a>, can also be played without touching the strings by using <a href="Audio_feedback" title="Audio feedback">audio feedback</a>. When an electric guitar is plugged into a loud, powerful guitar amplifier with a <a href="Loudspeaker" title="Loudspeaker">loudspeaker</a> and a high level of <a href="Distortion_(music)" title="Distortion (music)">distortion</a> is intentionally used, the guitar produces sustained high-pitched sounds. By changing the proximity of the guitar to the speaker, the guitarist can produce sounds that cannot be produced with standard plucking and picking techniques. This technique was popularized by <a href="Jimi_Hendrix" title="Jimi Hendrix">Jimi Hendrix</a> and others in the 1960s. It was widely used in <a href="Psychedelic_rock" title="Psychedelic rock">psychedelic rock</a> and <a href="Heavy_metal_music" title="Heavy metal music">heavy metal music</a>.

<p>There are three ways to change the pitch of a <a href="Vibrating_string" class="mw-redirect" title="Vibrating string">vibrating string</a>. String instruments are tuned by varying a string's tension because adjusting length or mass per unit length is impractical. Instruments with a <a href="Fingerboard" title="Fingerboard">fingerboard</a> are then played by adjusting the length of the vibrating portion of the strings. The following observations all apply to a string that is infinitely flexible (a theoretical assumption, because in practical applications, strings are not infinitely flexible) strung between two fixed supports. Real strings have finite curvature at the bridge and nut, and the bridge, because of its motion, is not exactly nodes of vibration. Hence the following statements about proportionality are approximations.

<p>The pitch of a string can also be varied by changing the <a href="Linear_density" title="Linear density">linear density</a> (mass per unit length) of the string. In practical applications, such as with <a href="Double_bass" title="Double bass">double bass</a> strings or bass <a href="Piano" title="Piano">piano</a> strings, extra weight is added to strings by winding them with metal. A string with a heavier metal winding produces a lower pitch than a string of equal length without a metal winding. This can be seen on a 2016-era set of gut strings for double bass. The higher-pitched G string is often made of synthetic material, or sometimes animal intestine, with no metal wrapping. To enable the low E string to produce a much lower pitch with a string of the same length, it is wrapped with many wrappings of thin metal wire. This adds to its mass without making it too stiff. The frequency is inversely proportional to the square root of the linear density:

<div class="mw-heading mw-heading2"><h2 id="String_length_or_scale_length">String length or scale length</h2></div>
<p>The length of the string from <a href="Nut_(instrumental)" class="mw-redirect" title="Nut (instrumental)">nut</a> to <a href="Bridge_(instrument)" title="Bridge (instrument)">bridge</a> on bowed or plucked instruments ultimately determines the distance between different notes on the instrument. For example, a double bass with its low range needs a <a href="Scale_length_(string_instruments)" title="Scale length (string instruments)">scale length</a> of around 42 inches (110&nbsp;cm), whilst a violin scale is only about 13 inches (33&nbsp;cm). On the shorter scale of the violin, the left hand may easily reach a range of slightly more than two octaves without <a href="Shifting_position" class="mw-redirect" title="Shifting position">shifting position</a>, while on the bass' longer scale, a single octave or a ninth is reachable in lower positions.
</p>
<div class="mw-heading mw-heading2"><h2 id="Contact_points_along_the_string">Contact points along the string</h2></div>

<p>In bowed instruments, the bow is normally placed perpendicularly to the string, at a point halfway between the end of the fingerboard and the bridge. However, different bow placements can be selected to change <a href="Timbre" title="Timbre">timbre</a>. Application of the bow close to the bridge (known as <i><a href="Sul_ponticello" class="mw-redirect" title="Sul ponticello">sul ponticello</a></i>) produces an intense, sometimes harsh sound, which acoustically emphasizes the upper <a href="Harmonic" title="Harmonic">harmonics</a>. Bowing above the fingerboard (<i><a href="Sul_tasto" class="mw-redirect" title="Sul tasto">sul tasto</a></i>) produces a purer tone with less overtone strength, emphasizing the <a href="Fundamental_frequency" title="Fundamental frequency">fundamental</a>, also known as <i>flautando</i>, since it sounds less reedy and more flute-like.
</p><p>Bowed instruments pose a challenge to instrument builders, as compared with instruments that are only plucked (e.g., guitar), because on bowed instruments, the musician must be able to play one string at a time if they wish. As such, a bowed instrument must have a curved bridge that makes the "outer" strings lower in height than the "inner" strings. With such a curved bridge, the player can select one string at a time to play. On guitars and <a href="Lute" title="Lute">lutes</a>, the bridge can be flat, because the strings are played by plucking them with the fingers, fingernails or a pick; by moving the fingers or pick to different positions, the player can play different strings. On bowed instruments, the need to play strings individually with the bow also limits the number of strings to about six or seven; with more strings, it would be impossible to select individual strings to bow. (Bowed strings can also play two bowed notes on two different strings at the same time, a technique called a <a href="Double_stop" title="Double stop">double stop</a>.) Indeed, on the orchestral <a href="String_section" title="String section">string section</a> instruments, four strings are the norm, with the exception of five strings used on some <a href="Double_bass" title="Double bass">double basses</a>. In contrast, with stringed keyboard instruments, 88 courses are used on a <a href="Piano" title="Piano">piano</a>, and even though these strings are arranged on a flat bridge, the mechanism can play any of the notes individually.
</p><p>Similar timbral distinctions are also possible with plucked string instruments by selecting an appropriate plucking point, although the difference is perhaps more subtle.
</p><p>In keyboard instruments, the contact point along the string (whether this be hammer, tangent, or plectrum) is a choice made by the instrument designer. Builders use a combination of experience and acoustic theory to establish the right set of contact points.
</p><p>In harpsichords, often there are two sets of strings of equal length. These "choirs" usually differ in their plucking points. One choir has a "normal" plucking point, producing a canonical harpsichord sound; the other has a plucking point close to the bridge, producing a reedier "nasal" sound rich in upper harmonics.
</p>
<div class="mw-heading mw-heading2"><h2 id="Production_of_multiple_notes">Production of multiple notes</h2></div>

<p>A single string at a certain tension and length only produces one note. To produce multiple notes, string instruments use one of two methods. One is to add enough strings to cover the required range of different notes (e.g., as with the <a href="Piano" title="Piano">piano</a>, which has sets of 88 strings to enable the performer to play 88 different notes). The other is to provide a way to <i>stop</i> the strings along their length to shorten the part that vibrates, which is the method used in guitar and violin family instruments to produce different notes from the same string. The piano and harp represent the first method, where each note on the instrument has its own string or <a href="Course_(music)" title="Course (music)">course</a> of multiple strings tuned to the same note. (Many notes on a piano are strung with a "choir" of three strings tuned alike, to increase the volume.) A guitar represents the second method—the player's fingers push the string against the fingerboard so that the string is pressed firmly against a metal fret. Pressing the string against a fret while plucking or strumming it shortens the vibrating part and thus produces a different note.
</p><p>Some zithers combine stoppable (melody) strings with a greater number of "open" harmony or chord strings. On instruments with stoppable strings, such as the violin or guitar, the player can shorten the vibrating length of the string, using their fingers directly (or more rarely through some mechanical device, as in the <a href="Nyckelharpa" title="Nyckelharpa">nyckelharpa</a> and the hurdy-gurdy). Such instruments usually have a fingerboard attached to the neck of the instrument, that provides a hard flat surface the player can stop the strings against. On some string instruments, the fingerboard has <a href="Fret" title="Fret">frets</a>, raised ridges perpendicular to the strings, that stop the string at precise intervals, in which case the fingerboard is also called a <i>fretboard</i>.
</p><p>Moving frets during performance is usually impractical. The bridges of a <a href="Koto_(instrument)" title="Koto (instrument)">koto</a>, on the other hand, may be moved by the player occasionally in the course of a single piece of music. Many modern Western harps include levers, either directly moved by fingers (on Celtic harps) or controlled by foot pedals (on orchestral harps), to raise the pitch of individual strings by a fixed amount. The Middle Eastern zither, the <a href="Qanun_(instrument)" title="Qanun (instrument)">qanun</a>, is equipped with small levers called <i>mandal</i> that let each course of multiple strings be incrementally retuned "on the fly" while the instrument is being played. These levers raise or lower the pitch of the string course by a microtone, less than a half step.

<p>A vibrating string strung on a very thick log, as a hypothetical example, would make only a very quiet sound, so string instruments are usually constructed in such a way that the vibrating string is coupled to a hollow resonating chamber, a <a href="Soundboard_(music)" title="Soundboard (music)">soundboard</a>, or both. On the violin, for example, the four strings pass over a thin wooden bridge resting on a hollow box (the body of the violin). The normal force applied to the body from the strings is supported in part by a small cylinder of wood called the <a href="Soundpost" class="mw-redirect" title="Soundpost">soundpost</a>. The violin body also has two "f-holes" carved on the top. The strings' vibrations are distributed via the bridge and soundpost to all surfaces of the instrument, and are thus made louder by matching of the <a href="Acoustic_impedance" title="Acoustic impedance">acoustic impedance</a>. The correct technical explanation is that they allow a better match to the <a href="Acoustic_impedance" title="Acoustic impedance">acoustic impedance</a> of the air.
</p><p>It is sometimes said that the sounding board or soundbox "amplifies" the sound of the strings. In reality, no power amplification occurs, because all of the <a href="Energy" title="Energy">energy</a> to produce <a href="Sound" title="Sound">sound</a> comes from the vibrating string. The mechanism is that the sounding board of the instrument provides a larger surface area to create <a href="Sound_wave" class="mw-redirect" title="Sound wave">sound waves</a> than that of the string and therefore acts as a matching element between the acoustic impedance of the string and that of the surrounding air. A larger vibrating surface can sometimes produce better matching; especially at lower frequencies.
</p><p>All <a href="Lute" title="Lute">lute</a>-type instruments traditionally have a bridge, which holds the string at the proper action height from the fret/finger board at one end of the strings. On acoustic instruments, the bridge performs an equally important function of transmitting string energy into the "sound box" of the instrument, thereby increasing the sound volume. The specific design, and materials used in the construction of the bridge of an instrument, have a dramatic impact upon both the sound and responsiveness of the instrument.
</p><p>Achieving a tonal characteristic that is effective and pleasing to the player's and listener's ear is something of an art and craft, as well as a science, and the makers of string instruments often seek very high quality woods to this end, particularly <a href="Spruce" title="Spruce">spruce</a> (chosen for its lightness, strength and flexibility) and <a href="Maple" title="Maple">maple</a> (a very hard wood). Spruce is used for the sounding boards of instruments from the violin to the piano. Instruments such as the banjo use a drum, covered in natural or synthetic skin, as their soundboard.
</p><p>Acoustic instruments can also be made of artificial materials, such as <a href="Carbon_fiber" class="mw-redirect" title="Carbon fiber">carbon fiber</a> and <a href="Fiberglass" title="Fiberglass">fiberglass</a> (particularly the larger, lower-pitched instruments, such as cellos and basses).
</p><p>In the early 20th century, the <a href="Stroh_violin" title="Stroh violin">Stroh violin</a> used a diaphragm-type <a href="Resonator" title="Resonator">resonator</a> and a metal horn to project the string sound, much like early mechanical gramophones.

String instrument players can electronically amplify their instruments by connecting them to a <a href="PA_system" class="mw-redirect" title="PA system">PA system</a> or a <a href="Guitar_amplifier" title="Guitar amplifier">guitar amplifier</a>.

</p><p>Amplified string instruments can be much louder than their acoustic counterparts, so musicians can play them in relatively loud rock, blues, and jazz ensembles.
